8.198. Term::ReadLine
Frontend to other ReadLine packages.
Currently interfaces to Term-ReadLine, which is available on CPAN.
Defines the variables $IN and
$OUT, which return the filehandles for input and
output, respectively, or undef if Readline input
and output cannot be used for Perl. Provides the following methods.
| new |
$term = new Term::ReadLine 'name'
Constructor. Returns the handle for subsequent calls to other
ReadLine methods. Argument name is the
name of the application. Optionally can be followed by two arguments
that are globs specifying input and output filehandles.
| addhistory |
$term->addhistory(line)
Adds line to the input history.
| Features |
$term->Features
Returns a reference to a hash whose keys are features present in the
current implementation and whose values are assigned to each feature.
Several optional features are used in the minimal interface:
appname
Should be present if the first argument to new is
recognized
minline
Should be present if MinLine method is not a dummyautohistory
Should be present if lines are put into history automatically (maybe
subject to MinLine)
addhistory
Should be present if the addhistory method is not
a dummy
| findConsole |
$term->findConsole
Returns array of two strings containing the most appropriate names
for input and output files, using the conventions
<$in and >$out.
| MinLine |
$term->MinLine([size])
With size argument, serves as a
recommendation on minimal size of line to be added to history.
Without an argument, does not add anything to the history. Returns
the old value.
| ReadLine |
$term->ReadLine
Returns the actual package that executes the commands. Some possible
values are Term::ReadLine::Gnu,
Term::ReadLine::Perl, or
Term::ReadLine::Stub.
| readline |
$term->readline(prompt)
Prompts for input line and gets the result. Removes trailing newline
and returns undef at end-of-file.
